What really causes your vehicle to rust?
Moisture. This moisture combined with road salt, mud, or air pollutants in contact with your vehicle's steel provides ideal conditions for rust to occur.

Will certain areas of my vehicle corrode faster than others?
Your vehicle will corrode first in the areas where moisture is allowed to sit and collect rather than drain or evaporate. These areas include seams, crevices, welds, or pockets where road dirt and salt accumulate and hold the moisture against the steel.

Can vehicle manufacturers solve the rust problem?
Manufacturers have made many improvements since the early ‘80s by using galvanized steel, better paint, and by improving drainage and ventilation. But, in the Northeast United States (the Rust Belt) unless they discontinue the use of steel, rust will happen—it's only a question of time.

What if my car already has rust?
If the corrosion is not bad enough to require bodywork, Carwell’s T-32 rust inhibitor, which is sprayed under pressure, will penetrate the existing corrosion and control further oxidation — significantly reducing further spreading of corrosion.

Does my vehicle have to be washed and clean before I can have it treated?
Yes and no. The Carwell product will penetrate light road dirt and effectively treat the metal on your vehicle. However, if the vehicle is packed with mud and other debris, it should be washed prior to being serviced. If our service technicians spot small areas of excessive dirt, they will power wash them prior to application. But, if the vehicle is too dirty, they will not be able to treat it.

Will the product remove existing rust?
No. It is not designed to remove existing corrosion. Carwell’s T-32 rust inhibitor is designed to penetrate to the good metal and set up a barrier to repel moisture and contaminants.

Can you come to me?
If you are a fleet manager or operator, please see our Fleet Services section for information on our Mobile Service.

How is it applied?
Carwell is atomized under high pressure which pushes the product deep into the seams, cracks, and crevices where corrosion starts. Once applied, the product removes the moisture in these areas and provides a strong adherence to these surfaces, remaining active with excellent "creeping" and self-healing abilities.

How is Carwell different than undercoating?
While an undercoating does provide protection to your vehicle's undercarriage, the protection stops there. And when undercoating chips, it leaves an area where road salts can penetrate and be trapped resulting in a higher potential of corrosion. Carwell provides protection to your whole vehicle and it cannot be chipped or cracked. The product creeps and crawls into seams, cracks, and crevices where corrosion begins, and provides an active barrier between the metal and the causes of corrosion

Do you have to reapply every year?
Yes. Just as we perform annual maintenance on our vehicle, and change the oil to maintain its effectiveness, Carwell’s T-32 rust inhibitor needs to be reapplied annually to maintain its effectiveness. When you bring your vehicle to us each year, you will receive a complete reapplication of our T-32 rust inhibitor as if your vehicle is being serviced for the first time. Annual service is not a "touch-up" or an inspection.

Does the application have to be done on a dry day?
No. The Carwell T-32 rust inhibitor has the ability to penetrate moisture effectively on metal and provide an insulating barrier.

What is the process?
Carwell is applied to your vehicle in all of the following areas:

Undercarriage: the entire undercarriage is treated; care is taken to avoid brakes, belts,
and exhaust.

When the application is completed, the exterior of your vehicle will be pressure washed to
remove all excess product from the windows and the body.

Do you drill holes in the car?
Only when necessary to access the inner compartments such as doors, rocker panels, window post area, etc. If we can access without drilling, we use existing holes provided by the manufacturer. It is essential to get into the inner compartments because that is where corrosion starts.

Will the product harm electrical wiring and electrical sensors?
No. Carwell’s T-32 rust inhibitor is a petroleum-based chemical which is dialectic, and it actually insulates electrical wiring. We do avoid getting overspray on the electrical sensors during the application process.

What if my car is mostly plastic?
Plastic components have to be attached to metal clips or supports and Carwell’s T-32 rust inhibitor prevents corrosion in those areas, as well as the many other important parts of a vehicle.
